Am relatively new to this game, but I seem to remember being told, by someone at some point that long acting insulin dose should roughly be the same as the quick acting doses, over the course of the day…
You seem to be taking twice as much fast acting as long acting…..
I find adding vegetables, or fibre, or roughage to my meals flattens out the spike somewhat.
There is a diet ‘guru’ who advocates eating your plate of food in a certain order and eating some kind of pickle/salad before the ‘main event.
Even a minimal amount of light exercise seems to have a flattening effect on my ‘spikes’…
